I now own a 1984 Gsl and it was known that it was leaking oil when i bought it . Fortunatly i have found that the leak is a lot less serious then i thought it was going to be. It appears to me that there is a drip coming from the bottem of the oil cooler and my question is " is this most likely the o-rings at the bottem of the bee hive cooler setup?" Also there are a few leaks coming from the drivers side rear of the oil pan so ive talked to a few people and i believe that this is simply the Oil pan Gasket. Is this a hard job to replace it?
